Pyraminx · top 5.2% of 129,321 all-time · competing since March 2024 · 2024TSOG01

Bat-Erdene Tsog-Erdene has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 3.43, set at Mongolian Championship 2025, puts him in the top 5.2% of the 129,321 people who have ever been ranked in the event, and 47th in Mongolia. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 8 competitions since March 2024, he has put 199 official solves on the record across six events. Solve to solve, his 3×3 times vary about 15% around a typical one; 81% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 41.28 in March 2024 to 12.63, a 69% improvement. He has entered eight competitions, more competitions than 90% of everyone who has ever competed.

The story so far

Competitions

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
